Oxalic Acid 99.6% CAS 144-62-7: Solving Industrial Purity and Supply Challenges
In leather processing, inconsistent oxalic acid purity can lead to uneven cleaning results and damaged hides, while mining operations face costly delays when reagent quality fluctuates. We’ve witnessed these issues firsthand over 10+ years of serving industrial clients—impurities causing equipment corrosion, batch variations disrupting production schedules, and unreliable suppliers failing to meet urgent orders.
Stable Supply of High-Purity Industrial Oxalic Acid
Our Oxalic Acid 99.6% CAS 144-62-7 addresses these critical pain points with consistent quality and reliable supply. As a leading chemical export platform with self-operated import-export rights, we maintain 6,000 tons/month production capacity to fulfill large-scale orders, supporting industries from leather manufacturing to mining operations. Our strict quality control ensures each batch meets the 99.6% purity standard, eliminating the variability that plagues industrial processes.
Key Industrial Applications
Industrial Oxalic Acid finds essential use in leather cleaning for removing lime and other impurities during tanning, where its dicarboxylic acid properties effectively break down mineral deposits without damaging collagen fibers. In mining, it serves as a reducing agent for mineral processing and metal extraction, particularly in separating rare earth elements. Additionally, it functions as a cleaning agent for stones and metal surfaces, leveraging its solubility in water and ethanol to dissolve rust and scale deposits in industrial equipment.
The Critical Role of Purity and Specifications
99.6% purity is not arbitrary—higher purity minimizes副反应 in leather treatment, ensuring consistent hide quality and reducing chemical waste. The medium strong acidity (pKa1 1.27) provides optimal reactivity for mining applications without excessive corrosiveness to processing equipment. With a melting point of 101-102ºC and boiling point of 365.10ºC, our oxalic acid maintains stability under industrial processing temperatures, preventing decomposition that could compromise product performance. The white powder form ensures uniform mixing in aqueous solutions, critical for achieving consistent results in large-scale operations.
Benefits of Reliable Oxalic Acid Sourcing
Using certified Industrial Oxalic Acid reduces production risks compared to low-quality alternatives. Our ISO9001 and SGS certifications guarantee compliance with international industrial standards, avoiding costly rejections at customs or production failures due to impurities. With 150,000 tons annual supply capacity, we eliminate the supply chain disruptions that force factories to halt operations. Leather Cleaning Oxalic Acid from our stable supply chain ensures year-round production consistency, while mining operations benefit from predictable reagent quality that maintains processing efficiency and reduces equipment maintenance costs.
Our Quality Assurance Commitment
Every batch of Oxalic Acid undergoes rigorous testing through HPLC and titration methods to verify purity, with heavy metal content strictly controlled below industrial limits. We provide a Certificate of Analysis (COA) with each shipment, detailing parameters including solubility, density, and impurity levels. Our production facility operates under GMP-like standards for industrial chemicals, with 24/7 monitoring of hydrolysis processes to ensure consistent product quality. Should any batch fail to meet specified parameters, we offer full replacement or refund—no questions asked. Our technical support team, with an average of 8 years in chemical process engineering, provides guidance on optimal usage and handling for specific industrial applications.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA and MSDS, with detailed test results for key parameters including assay, water content, and insoluble matter. For critical applications requiring additional verification, we can provide full HPLC or GC-MS spectra upon request. All documentation is available in English and complies with EU REACH and US TSCA requirements, facilitating customs clearance in major export markets.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
